A revisionist account of the Tejano experience in south Texas from its Spanish colonial roots to 1900.
The quarter century from 1964 to 1989 was the "time of the generals," the most clearly defined era of military rule and influence in the history of Latin America. The effects of this rule were most evident in Argentina, Brazil, Peru, and Chile, where French- and German-style military professionalism developed into professional militarism. Frederick M. Nunn shows that the mentality of Latin American generals is typical of a worldwide military ethos but that its application is unique in the context of individual countries. In detailing the pervasiveness of this ethos worldwide, Nunn enables a better understanding of the willingness of Latin American military leaders to intervene in government, and of their activities once in power.
This volume contains the Proceedings of the Fifth Scientific Meeting of the Spanish Astronomical Society (Sociedad Espanola de Astronomfa, SEA). The meeting was held at the Universidad de Castilla La Mancha in Toledo, from September 9 to 13, 2002. The event brought together 219 participants who pre sented their latest results in many different subjects. In comparison with the previous scientific meetings of the Society, the numbers of oral talks and poster contributions (122 and 64, respectively) are rapidly increasing, confirming that the SEA conferences are becoming a point of reference to assess the interests and achievements of astrophysical research in Spain. During the meeting, the SEA...
In the mathematical description of a physical or biological process, it is a common practice \0 assume that the future behavior of Ihe process considered depends only on the present slate, and therefore can be described by a finite sct of ordinary diffe rential equations. This is satisfactory for a large class of practical systems. However. the existence of lime-delay elements, such as material or infonnation transport, of tcn renders such description unsatisfactory in accounting for important behaviors of many practical systems. Indeed. due largely to the current lack of effective metho dology for analysis and control design for such systems, the lime-delay elements arc often either neglected or poorly approximated, which frequently results in analysis and simulation of insufficient accuracy, which in turns leads to poor performance of the systems designed. Indeed, it has been demonstrated in the area of automatic control that a relatively small delay may lead to instability or significantly deteriora ted perfonnances for the corresponding closed-loop systems.
